Contains three applications:

MORSE CODE TUTOR
by Capt. S M McCrory, USN
FLASHING LIGHTS PRACTICE PROGRAM
by Navy Personnel Research & Development Center
MORSE CODE TRAINING PROGRAM
CW v3.11A by Lee Murrah
Variable-speed Morse code generator
[not in the menu; play via this link]
MORSECOD.BAS by Dick Conklin, call sign: N4AT

The first two appear to be developed in-house and can likely be considered public domain. Copyright status of works by the federal government of the United States.

CW by Lee Murrah was a popular shareware Morse Code trainer, with later versions named Super Morse.

Emulation timing issues:

DOSBox uses Ctrl-F11 and Ctrl-F12 to adjust emulated CPU speed.
Reload the page to reset CPU speed.
MORSE CODE TUTOR is largely unaffected by the CPU speed. You can decrease the CPU speed to introduced a pause after the 'fail buzzer' (before Morse plays again). Mash Ctrl-F11 a few times to do this.
FLASHING LIGHTS PRACTICE PROGRAM might run a little fast at the default DOSBox CPU speed but is usable. From a rough stopwatch test, it's 2% to 15% fast depending on whether it's using the CODEX or PARIS standard.
MORSE CODE TRAINING PROGRAM (aka "CW") plays Morse code inhumanly fast. Four separate methods to fix it:

Mash Ctrl-F11 maybe 12 times or so; OR
Adjusted timing within the program itself to work with Dosbox's default CPU speed: Utilities > Timing > 32766 (which is the maximum slowdown value, which is not quite enough but within 5% of what it's meant to be); OR
Play CW v3.12 here with the original color palette, where the timing value is pre-adjusted; OR
Play the newer Super Morse from the same author, which does not have CPU-dependent audio speed.

Files:

Files from all three applications and from the menu system are all mixed together in the root directory.
CW has all its original files (matching v3.12), except the configuration (CW.CFG) is altered; and the user manual is missing (CW.DOC).
Files belonging to CW are: ANTENNAS.CW CITIES.CW CW.CFG CW.COM CWGUIDE.TXT FEEDBACK.FRM GENIE.INF GROUPS.1 GROUPS.2 GROUPS.CW HAMRADIO.INF JOBS.CW MYGROUP.CW NAMES.CW PAIRS.CW PROBLEM.RPT README.1ST RIGS.CW WORDS.CW
